Description

Tripartite motif-containing 28, also known as transcriptional intermediary factor 1b (TIF1b) and KAP1 (KRAB-associated protein-1), is a protein that in humans is encoded by the TRIM28 gene. The protein encoded by this gene mediates transcriptional control by interaction with the Kruppel-associated box repression domain found in many transcription factors. The protein localizes to the nucleus and is thought to associate with specific chromatin regions. KAP1 is a ubiquitously expressed protein involved in many critical functions including: transcriptional regulation, cellular differentiation and proliferation, DNA damage repair, viral suppression, and apoptosis. Its functionality is dependent upon post-translational modifications. Phosphorylation of KAP1 acts as a deactivator of the protein in many of its mechanisms while sumoylation acts as an activator.

Application Notes

Optimal dilution of the TRIM28 antibody should be determined by the researcher.

Immunogen

Amino acids 699-835 of human TRIM28 were used as the immunogen for the TRIM28 antibody.

Storage

After reconstitution, the TRIM28 antibody can be stored for up to one month at 4oC. For long-term, aliquot and store at -20oC. Avoid repeated freezing and thawing.
